Estudo de Caso: Dispositivo de drenagem de transposição de talvegues – bueiros na Avenida Progresso, em Senador Canedo - GO

Abstract

This work presents a case study of the construction of three culverts on Avenida Progresso, in Senador Canedo - GO. With the development of metropolitan areas, the need to intervene in the transport infrastructure between cities becomes increasingly crucial due to urban growth in the most developed areas. These interventions involve physical changes, such as the construction and duplication of paved roads, which results in the waterproofing of soils, changes in relief and watercourses. When building and expanding rural or urban roads, it is essential to include drainage devices in the projects to ensure the correct drainage of rainwater. Various types of devices, such as culverts, bridges, storm drains, curbs, gutters and rainwater galleries, can be used alone or together to perform this function. This case study sought to present a detail of the project and the results of monitoring and monitoring the construction process of three culverts in a segment of Avenida Progresso, which connects Goiânia to Senador Canedo, in Goiás. The duplication of this road mainly meets the needs of residents urban workers and workers in the construction sector in the Senador Canedo region, due to the growth of subdivisions and horizontal condominiums in the municipality. To support and apply this case study, manuals and technical standards from the National Department of Transport Infrastructure - DNIT were consulted, as well as works such as those by JABOR (2005) and VERDUM et al (2016). In parallel, a study and data collection of the project was carried out, the contextualization of the place where the culverts were implemented and the monitoring and monitoring of the work. The project presented data consistent with the methodology indicated in the DNIT Drainage Manual (2018) and presented adequate execution, following the existing service specifications for each project solution, technological and topographic controls were carried out to ensure execution in accordance with the project. To avoid the risk of erosion and silting, adjustments were made to the land at the downstream mouths by building a gabion and filling rocks in the channel and replanting the land where the mouths upstream of the culverts are located. During the on-site inspection after approximately one year of the constructed culverts, a lack of maintenance in the culverts was identified, which could cause clogging and failure in the efficiency of the proposed drainage system.
